Answer: 1.018

Step-by-step explanation:

The pH level of a substance indicates the concentration of hydrogen ions (H^{+}) in a solution and is calculated by:

pH=-log(H^{+})

In this case the hydrogen ion concentration is 0.095811180 M, where

M=\frac{moles}{volume}. Hence:

pH=-log(0.095811180 M)

pH=1.018 This means this new substance is acid
